1. Yuav ua li cas txheeb xyuas cov hlau yeeb nkab?
Xim: Stainless hlau feem ntau muaj npub nyiaj-grey ua tiav; Tooj liab liab liab-xim av (tarnishes rau ntsuab); Txhuas yog lub teeb ci txho nrog matte saib; Inconel / Nickel alloys yuav muaj lub ntsej muag daj lossis tsaus dua dej tint.
Lub cim: Txheeb xyuas cov nyiaj muas / engravings (piv txwv li, "304" rau incenless cov hlau, "718" rau nickel alloys, lossis "A312" rau cov kav dej stainless hlau).
Kev ua cev tub: Xeb (liab-xim av) qhia cov hlau hlau; Stainless hlau lossis inconel tiv taus xeb tab sis tuaj yeem qhia cov khaub ncaws tsis sib haum xeeb hauv ib puag ncig hnyav.
Cov hlau ferrous (carbon hlau, qee cov hlau stainless xws li 430) yog sib nqus.
Tsis-ferrous hlau (Aluminium, tooj liab, Nickel alloys zoo li Inconel, Austenitic Stainless hlau zoo li 304/316) tsis muaj hlau nplaum.
Denser hlau (tooj liab, tsis raug, txhuas) xav tias hnyav dua li cov loj dua (txhuas, titanium) ntawm tib qho loj.
Khawb qhov chaw nrog cov ntaub ntawv: Cov mos mos (txhuas, tooj) kos tau yooj yim; Cov hlau tawv (stainless hlau, inconel) tiv taus screening.
Chaw Kev Ntsuam Xyuas: Siv reagents (piv txwv li, nitric acid rau stainless hlau, uas yuav tsim cov xim hloov). Piv txwv li, Inconel reacts maj mam rau cov kua qaub piv rau cov hlau.
Xeem Kev Ntsuas: Sib tsoo cov yeeb nkab tsim cov zaub ntsuab-carbon steel ua rau ci ntsa iab, ntev ntev; stainless hlau muaj luv, duller lub txim taws; Nickel alloys (inconel) ua rau ob peb los tsis muaj lub txim taws.
X-tshav fluorescence (XRF) lossis kho qhov muag tawm ntawm lub zog (OES) rau meej tagnrho alloy muaj pes tsawg leeg.
2. Dab tsi yog qhov zoo tshaj li inconel?
Zoo dua lub zog-rau-qhov hnyav piv (sib zog dua li inconel thaum tswj lub zog siab).
Superior corrosion tsis kam nyob rau hauv seaterater thiab chlorine ib puag ncig.
Qhov zoo tagnrho rau Aerospace (Airframrams) thiab cov ntawv thov marrine uas qhov hnyav yog qhov tseem ceeb.
Outperforms inconel nyob rau hauv ib puag ncig heev ib puag ncig (piv txwv li, concentridrated acids, chlorine, sulfuric acid).
Zoo dua tsis kam rau pitting thiab kev ntxhov siab corrosion tawg hauv kev tawm tsam.
Siab melting taw tes (~ 3,422 Qib vs. Inconel 718's ~ 1,399 Degree) thiab zoo dua siab-kub zog, tab sis nkig thiab hnyav. Siv hauv foob pob ua ntxig.
3. Dab tsi yog tus pas nrig siv rau weld inconel?
Ernifecr-2 (ANS A5.14) yog tus qauv ua kom phim 718's niobium, molybdenum lub zog, ua kom lub zog nick-kub.
Ornicr-3 (aws A5.14) yog siv, raws li nws tsom iav 600's npib tsib xee-chromium tshuav nyiaj li oxidation tsis kam.
ENLICRMO-3 (AWS A5.14) yog qhov zoo tshaj plaws, muab cov molybdenum thiab niobium ntxiv rau corrosion tsis kam nyob rau hauv kev ua txhaum cai.
ErnifecRMO-1 (AWS A5.14) ntais ntawv 825's Titanium thiab tooj liab cov ntsiab lus, tseem ceeb rau cov sulfuric acid.
4. Dab tsi yog qhov zoo tshaj plaws los txiav inconel?
Siv cov dej siab ntawm cov dej sib xyaw nrog abrasive grit (piv txwv li, garnet) txiav los ntawm tsis muaj cua sov, zam kev ua haujlwm hnyav lossis thermal distortion. Qhov zoo tagnrho rau cov qauv ncaj qha, cov duab ua ke thiab yuag yuag kom tuab.
Siv cov ntshav hluav taws xob nrog cov roj kub highized ionized kom yaj thiab tawg khoom. Yuav tsum muaj lub zog ntshav siab ({100+ amps) thiab cov tshuaj tshwj xeeb (piv txwv li inconel tiv thaiv. Haum rau tuab kav dej tab sis yuav tawm ib thaj chaw kub-cuam tshuam (hz).
Lub High-fais fab laser (co₂ lossis fiber ntau) melts thiab vaporizes inconel, muab qhov siab precision rau nyias mus rau hauv cov tuab tuab mus rau nyias. Ua haujlwm zoo tshaj plaws nrog khoos phis tawj suav sau (cnc) qhov tseeb, tab sis nws tuaj yeem tsim cov chaw kub-kev cuam tshuam.
Pob zeb diamond lossis cubic boron nitride (CBN) log, siv nrog kev txiav tawm qeeb thiab ua kom txias txias (dej txias) kom tiv thaiv kev kub ntxhov thiab lub log hnav. Haum rau me-txoj kab ntawm cov kav dej tab sis tsis muaj txiaj ntsig zoo rau cov ntaub ntawv tuab.
